APPARATUS FOR FILTERING AND REFRIGERATING WATER.

SPECIFICATION forming part of Letters Patent No. 277,931, dated May 22,1883.

Application filed August 29, 1882. v (No model.)

To all whom it may concern Be it known that I, SAMUEL F. REYNOLDS, acitizen of the United States, residing at Auburn, in the county ofCayuga and State of New York, haveinvented certain new and usefulImprovements in Apparatus for Filtering and Refrigerating \Vater; and Ido declare the following to bea full, clear, and exact description ofthe invention, such as will enable others to skilled in the art towhiclrit appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification. :5 Thisinvention relates to an improved ap- -paratus for filtering andrefrigerating water for domestic and other purposes; and it consists ina method of cooling water by bringing it in contact with a chambercontaining cooled air or other refrigerating material; and also incertain peculiarities in the construction, arrangemeut,, and combinationof the various parts of a water filtering and cooling device, ashereinafter more fully described and claimed. In the annexed drawings,illustrating my invention, Figure l is asectional side elevation ofawater cooling and filtering apparatus, showing one form of applying myinvention. Fig. 2 represents a side and an end view of 0 my improvedfilter with perforated plates or screws.

Like letters are used to designate like parts. Referring to thedrawings, A denotes a power-fan that is connected with a coil, B, in- 35 closed in a tank or ice-receptacle, G. The upper end or branch, B, ofthe coil B may be extended vertically or in any desired direction forthe purpose of conveying cooled air'to the chamber D of a water-cooler,or to water 0 tanks or refrigerators in various parts of the samebuilding or in different buildings. As

' represented in the drawings, the cooled air chamber D is connectedwith the cold-air coil B by'meaus ofa pipe, B extending from the 5pipeBY to the cap E of the cold-air chamber. This coldair chamber ispreferably composed of cast-iron, and has the form of a bowl. It

is suspended in the water tank or chamber F in such a way as to form theupper part or 0 wall of the same, and is itself provided with aconcavo-convex cap or cover, E, as before described. The cold-airchamber D and water chamber F are inclosed in ajacket or casing, Gr,constructed of any desired material and in any suitable form. Thiscasingis designed to be supported in any appropriate manner, aud isprovided with a faucet, H, that communicates with the water-chamber F.The lower part of the cold-air chamber or how] D is provided internallywith an annular projection. to, through which is passed the upper end ofa vertical pipe, I, that passes down through the water-receptacle F andfilter K. This unnular projection is provided at; the top with anannular groove or recess for the reception of packing I), and a nut, c,is attached to the upper part of the pipe I for the purpose of securingit in position. The filter K is connected by screw-threads or otherwisewith an opening in the bottom of the water-tank and its inclosingjacket,and is provided with a tlange or collar, (1, that lits beneath the edgeof the opening in the jacket, the upper part of the collar, which may beeither fixed or movable, being recessed for the reception of suitablepacking, 0, as shown in Fig. 1. The upper part of the filter-tube Kisprovided with a "finely-perforated plate or screen,f, and similarscreens 9 71, are also arranged at intervals within the filter. Thesescreens are also perforated centrally for the passage of the waste-pipeI, which also passes through a removable cap, '5, at the lower end ofthe filter-tube, and is there secured by a nut, 70. The cap i isprovided with a nozzle and mud-valve,m. A feed-pipe, L, is arranged toenter the filter at a point below the fixed screen h, and is providedwith a valve, 12, for governing the supply of water. The screen It isfixed within the filter K at a suitable point to allow an ample spacebeneath for the deposit of sediment, and the feed-pipe L is arranged toenter the filter at such a height that it cannot possibly disturb thesediment deposited in the lower end of the filter. It will thus be seenthat after the sediment is separated it the force of the incoming water;but will re main in the bottom of the filter until it is re movedthrough the mud-valve m, or by detaching and cleansing the cap Above thescreen h are placed layers of gravel, with an intermediate layer ofcharcoal,

will not again be carried up into the filter by or any other suitablefiltering material may be used, the whole being covered by a movableorloose-fitting screen, g, above which is placed a quantity of sand orother filtering substance. The plate or screen 9, being placed looselywithin the filter between the sand and gravel, will rise under thepressure of the upward flow of water, and thus pack the sand tightly.

In arranging this apparatus within a building, I prefer to place thecoil B and ice-tank .O in the basement or cellar; or the coil may beplaced in an ice-house or other suitable situation incontact withrefrigerating material. The coil B is connected at one end with the fanA, while its 'other'end is extended to the place to be cooled. The coilmay be surrounded with ice alone or with ice and water. The air, forcedby the fan and cooled by its proximity to the refrigerating material, isthus readily conducted to any desired apartment or to the water-tanks orcoolers located therein.

It is obvious that the air-conducting pipes may be covered in anysuitable manner, or may be laid in the ground or be embedded in thewalls of a building, for the purpose of protectin g them from the accessof heat.

It will be seen that when cold air is introduced to the chamber or bowlD, which is in contact with the water contained in the chamher I thewater is thus readily cooled without being brought directly in contactwith ice, thus avoiding the ordinary necessity of conveyiug ice from oneapartment or building to another.

If desired, the cap E and air-conducting pipe B may be disconnected fromthe jacket or casing G, and the bowl D and water'chamber F be used aloneor simply in connection with the filtering devices above described. Inthis case ice will be placed in the bowl immediately above thewater-chamber. The pipe I serves as an exit for air when the entireapparatus is used, and for melted ice when ice is placed in the bowl D.It will be observed that the form of the bowl or chamber D is such thatthe ice or the cold air will chill the material of which the bowl iscomposed at the most effective point-that is to say, at the point wherewater from the filter enters the water-chamber-and it also enables thebowl 'to present a larger cold surface all the way up to the faucet thanwould be practical if its form were'rectangular instead of being asshown.

Bypassing the water-supply upward through the filter and arranging thefeed-pipe and filtering material in the manner described, it will beseen that the water conducted to the cooling-chamber will be filtered inthe most effective manner.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination of the jacket Gr, waterchamber F, faucet H,refrigerating bowl or chamber D, suspended in the water-chamber, andhaving cap E and internal annular projection a, the filter K, havingfeed-pipe L, perforated screensfg h, and cap 2', the'waste-pipe I, nuts0 7r, collar (1, and packing b a, substantially as described.

2. The combination of the fan A, refrigerating-tank G, coil B, inclosedin said tank, the jacket or casing G, watenchamber F, refrigerating bowlor chamber D, suspended in the water-chamber, the concavo-convex cap E,pipe B connecting the coil B and chamberD, the faucet H and filter K,communicatingwith the waterchamber, the waste-pipe I, filterscreensfg h,cap 2', having mud-valve m, and the feed-pipe L,eutering the filter, allsubstantially. as shown and described.

3. The method of filtering and cooling water, consisting in conveyingthe water vertically through a tube containing filtering material,whereby the sedimentis separated and deposited in the bottom ofsaidfilter, and then bringing the water in contact with a chamber con-.taining cold air, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
